Information on air-conditioning
compressorThe air-conditioning compressor:
– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures be-
low approx. 37.4°F (3°C) and cannot be
switched on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time,
however, it is a good idea to ventilate the
interior briefly with the windows open.
Notes on operation
Depending on the outside temperature and humid-
ity, condensation can drip from the evaporator
and form a pool under the car.
This is normal and not a sign of leakage.
If uncooled air flows out when the lowest temper-
ature has been set (“LO”), switch off the air-condi-
tioning compressor and have the fault remedied at
an authorized Porsche dealer.
REST modeUsing engine residual heat
The residual heat of the engine can be used to
heat the interior up to 20 minutes after the ignition
has been switched off.
fPress REST button N.
The air-conditioning settings cannot be
changed in REST mode.
Ending the function
fPress REST button N.
Note on operation
If the battery positive voltage is too low, REST
mode is automatically ended.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 108.

Parking AidsParkAssistParkAssist provides a visual and acoustic indica-
tion to the driver of the distance between the
vehicle and a large obstacle.
ParkAssist is switched on automatically when the
engine is started and remains active up to a speed
of approx. 9 mph (14 km/h).
ParkAssist is switched off automatically at high
speed. ParkAssist is switched on again auto-
matically when the speed drops below approx.
9mph (14km/h).
The selector lever position determines activation
levels for ParkAssist and the corresponding area
that is monitored.
Selector lever position:
–P – ParkAssist is not activated.
–R, N – ParkAssist is activated for the front and
rear areas.
–D, M – ParkAssist is activated for the front ar-
ea.Gearshift lever position:
–R– ParkAssist is activated for the front and
rear areas.
–In all other gearshift positions – ParkAssist
is activated for the front area.
Note

Risk of serious personal injury or death.
ParkAssist cannot detect small objects such
as children and pets.
Even when using ParkAssist, the driver is still
responsible for taking due care when park-
ing and when assessing obstacles.
